我正在使用：

Java 1.8
Selenium 3.5.0
Selenium Standalone Server 3.5.0
硒中心OS - RHEL 7
Geckodriver 18
Firefox 55

我有一个错误：

选择firefox的代码：

            public static WebDriver ff() {

            File firefoxfile = new File(PropertyReader.getProperty("firefox"));
            System.setProperty("webdriver.gecko.driver", firefoxfile.getPath());

            WebDriver wd = null;//new RemoteWebDriver(dc);

            try {
                URL url = new URL("http://" + TestRunner.SELENIUM_HUB + ":4444/wd/hub");
                FirefoxProfile fp = new FirefoxProfile();
                // set something on the profile...
                DesiredCapabilities dc = DesiredCapabilities.firefox();
                dc.setCapability("marionette", true);
                //dc.setCapability(FirefoxDriver.PROFILE, fp);

                wd = new RemoteWebDriver(url, dc);
            } catch (MalformedURLException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
            return wd;
    }

我认为Linux上geckodriver的路径出了问题。我尝试了几个选项：

/drivers/geckodriver
drivers/geckodriver
root/drivers/geckodriver
但没有成功

Linux上带geckodriver的目录中的pwd给了我：
/root/drivers

Answer 1

请将geckodriver更新到最新版本。

File firefoxfile = new File(PropertyReader.getProperty("C://users//geckodriver.exe"));
 System.setProperty("webdriver.gecko.driver", firefoxfile.getPath());

Answer 2

我遇到了同样的问题，并通过将系统属性设置为 geckodriver.exe 路径来解决此问题，如下所示：

System.setProperty("webdriver.gecko.driver","C:\\tech2\\selenium\\geckodriver.exe");

在实例化驱动程序之前设置属性。

我找到了解决方案here。这个问题似乎特定于selenium 3.x +。
